Question

Evaluate : $5.4\times 5$

Answer 1

Step 1 : Multiply the given decimals ignoring the decimal points

$$\begin{gathered} 54\times 5 \\ =270 \end{gathered}$$

Step 2 : Add the number of decimal places in each number . In the product obtained , place the decimal point after the same number of digits ( from right to left ) as the total number of decimal places.

Since , the total number of decimal places in the given decimals = $1$ ( $1$in $5.4$ ) .So ,we will place the decimal point after two digits from the right to left as $27.0$ .

Thus , $5.4\times 5$ = $27.0$ .
